Correlation between ACE2 in from cardiac tissue biopsies and genes from RAS system. Results are presented as the Log10 of the normalized mRNA fold induction. a Direct correlation between ACE2 mRNA expression and MAS1 receptor mRNA. b Direct correlation between ACE2 and AT1 receptor mRNA in cardiac biopsies (n = 72). c Direct correlation between ACE2 and ACE1 mRNA. d No correlation between ACE2 and ACE1 activity. e Effect of ACEi, ARBs or no RAS blockers prior to the CABG operation on ACE1 activity in the serum (n = 19)
